So I got one today. Sounds fine. Problem is the fretboard. Buzzing frets 10 - 15 G string, 3 through 6 G string. The guitar tech at sam ash noticed that the frets were not the same heights. He went to ajusting on it, mallet, pulling and glueing...straight edging it...the damn thing would rock it was bad. We both comented this typically doesnt happen with yamaha. They typically have really good QC. Thought he had it. Adjusted the action and the relief, checked it again. I took it home restrung it. The fret buzz was back. A new fret buzz at the first fret on the A string has shown up as well. I have never bought a bass with these problems off the bat. I really like the tone of the bass. It was the only one in stock. They are out of stock EVERYWHERE In the area. Im just worried about what will develop over time. Im worried Il never get the action to where I want it which is pretty low. Any recomendations?
